Features

Environmental lamp, preventing from Ozone inhalation
Real-time monitoring the lifetime of lamp and Tungsten lamp
Socket-Type lamp and Tungsten lamp
GLP self-check function:check the wavelength accuracy and Photometry accuracy,provide test report and power-off protection
Wavelength calibration, wavelength setting, change lamp source and dark current calibration automatically
SiO2 coating optical mirror, reduces the influence from outside

Photometry
Test Abs., Transmittance and Energy by fixed wavelength
Quantitative
a. Linear fit and Linear fit through zero two modes
Coefficient, Standard Sample input and Standard Sample read three modes to establish standard curve
b. Establish A=K1*C+K0, can search original data, graph curve, parameters settings
c. Can save 240 group curves, can test 240 data in each curve
d. Double wavelength, Triple wavelength test functions.
Kinetics
Used for time course scanning or reaction rate calculations△A/t, can search all data
Multi-Wavelength
Can test Transmittance and Abs. with 8 different wavelengths at most
Scanning
User can set the scan range from 190nm to 1100nm to test the max. Abs. peak value, can do derivation, arithmetical operationsto the graph.
Biology
6 methods: DNA/Protein, UV, Lowry, BCA,CBB and Biuret
